Benefits of technology

[0008] The invention provides for a drainage system for draining a fluid from a hardenable material as the fluid flows through an aperture formed in the hardenable material. The system includes a conduit having an outer surface defining an inner chamber and a length extending between distal ends with an axis extending along the length. A catch is supported by the outer surface of the conduit for directing the fluid from the aperture into the inner chamber. The catch includes a first tab extending along a portion of the length of the conduit and a second tab extending along a portion of the length of the conduit with the second tab radially spaced from the first tab about the axis for insertion into the hardenable material about opposing sides of the aperture to prevent collapsing of the conduit and to maintain a flow of the fluid from the aperture into the inner chamber.
[0010] The invention further provides for a catch for a conduit for draining a fluid from a hardenable material. The catch includes a base defining a length with the base being adapted for mounting to the conduit. The catch further includes a first tab extending from the base along the length and defining a first plane. In addition, the catch includes a second tab extending from the base along the length spaced from the first tab and the second tab defining a second plane angled relative to the first plane for inserting the first tab and the second tab into the hardenable material to prevent collapsing of the conduit and to maintain a flow of the fluid into the conduit.

Problems solved by technology

As the fluid flows into the expansion joint, changes in temperature cause the fluid to expand and contract, which can crack the concrete surfaces.

Embodiment Construction

[0026] Referring to the Figures, wherein like numerals indicate corresponding parts throughout the several views, a drainage system 20 is disclosed generally at reference numeral. As shown in FIGS. 1 and 2, the drainage system 20 is used below a hardenable material 22, such as a concrete driveway or sidewalk. Referring to FIGS. 3 and 4, the drainage system 20 includes a conduit 24 having an outer surface 26 defining an inner chamber 28. A length extends between distal ends of the conduit 24 with an axis A extending along the length. A catch 30 is disposed on the outer surface 26 of the conduit 24 and extends along at least a portion of the length of the conduit 24. The catch 30 includes a first tab 32 having a first tab length that extends along the catch 30. In one embodiment, the first tab 32 defines a first plane P1 that extends through the first tab 32 and through the axis A. The catch 30 also includes a second tab 34 having a second tab length equal to that of the first tab len...

Abstract

A drainage system for draining a fluid from a hardenable material as the fluid flows through an aperture formed in the hardenable material includes a conduit and a catch. The conduit has an outer surface defining an inner chamber. The catch is supported by the outer surface of the conduit for directing the fluid from the aperture into the inner chamber. The catch includes a first tab and a second tab that extend along a portion of the length of the conduit, and the second tab is spaced from the first tab. Both the first tab and the second tab are inserted into the hardenable material about opposing sides of the aperture to prevent a collapsing of the conduit and to maintain a flow of the fluid from the aperture into the inner chamber.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of application Ser. No. 60 / 756,156 filed Jan. 4, 2006, which is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The subject invention relates to system and method for draining a fluid from a hardenable material as the fluid flows through an aperture formed in the hardenable material. [0004] 2. Description of the Prior Art [0005] Drainage systems are important when working with concrete surfaces. Specifically, drainage systems may be used to move a fluid from an expansion joint between two concrete surfaces. As the fluid flows into the expansion joint, changes in temperature cause the fluid to expand and contract, which can crack the concrete surfaces. Therefore, it is necessary to move the fluid away from the concrete surface to reduce the fluid in the expansion joint. [0006] Various drainage systems are known in the art. One such dra...
